Edge Wound Heater (Bayonet Heater)

The Edge Wound Heater (Bayonet Heater) is specially designed for industrial heating applications where maximum heating power is required within a limited installation space. Its compact, high-power-density construction allows it to deliver efficient and uniform heat while occupying significantly less space than conventional rod-type heating elements. The heater uses a high-resistance strip that is precisely edge-wound onto high-aluminium ceramic bobbins, providing excellent electrical insulation, mechanical stability, and reliable performance at elevated temperatures. This advanced design enables the heater to achieve rapid heat transfer and consistent temperature distribution, making it suitable for demanding furnace operations where precise and dependable heating is essential. It can effectively replace traditional rod elements in furnaces that require higher power output, while also providing an efficient solution for converting existing gas-fired furnaces into electric heating systems. With its robust construction, easy installation, convenient replacement, and suitability for continuous industrial operation, the Edge Wound Heater offers a practical, energy-efficient, and reliable heating solution for modern furnace and heat-treatment applications.
